Section 1
Mandatory Energy Efficiency Labelling Scheme
1.
The Mandatory Energy Efficiency Labelling Scheme (“MEELS”) was introduced
through the Energy Efficiency (Labelling of Products) Ordinance (Cap. 598) (“the
Ordinance”), which was enacted on 9 May 2008. Under the Ordinance, energy labels
are required to be shown on all prescribed products for supply in Hong Kong to inform
consumers of their energy efficiency performance.
2.
The MEELS was implemented in phases. The initial and second phases have been fully
implemented since 9 November 2009 and 19 September 2011 respectively, covering
five types of prescribed products, namely room air conditioners, refrigerating
appliances, compact fluorescent lamps, washing machines and dehumidifiers. It is
estimated that these five electrical products together altogether account for about 60%
of the annual electricity consumption in the residential sector in 2012.
3.
A Code of Practice on Energy Labelling of Products (“CoP”) is approved and issued
under section 42 of the Ordinance. The CoP provides practical guidance for
requirements under the Ordinance. The latest edition of the CoP is available at the
website of the Electrical and Mechanical Services Department with the following link:
http://www.energylabel.emsd.gov.hk/en/doc/Integrated_Code_of_Practice_2014.pdf
4.
In order to help the general public in choosing energy efficient appliances and
capitalize further energy saving, it is considered advisable to include more products
into the MEELS.
5.
Sections 3 of this document outline the initial proposal of including televisions,
washing machines (exceeding 7kg but not over 10kg), room air conditioners (heat
pump), electric storage water heaters, electric rice cookers, induction cookers and
microwave ovens into the MEELS.
6.
Section 4 of this document invites views on the initial proposal of including televisions,
washing machines (7 kg < washing capacity ≤ 10kg), room air conditioners (heat
pump), electric storage water heaters, electric rice cookers, induction cookers and
microwave ovens into the MEELS on or before 30 June 2015.

Section 3
Proposals on Third Phase of MEELS for the Following Products
Section 3.1 - Televisions
9.
Considerations for Inclusion into the MEELS
The following information has been taken into account in considering the inclusion of
televisions into the MEELS:
(i)
Overseas Practices:
– Televisions are widely covered in the mandatory labelling schemes of
overseas economies (including Australia, China, the European Union,
Singapore, South Korea and the United States).
(ii) Test Standards:
– International test standards are available for energy efficiency performance
measurement of televisions at on-mode and standby operation, and are
widely adopted by overseas economies.
(iii) Availability of Testing Laboratories:
– Accredited testing laboratories are available in Hong Kong for testing the
energy efficiency performance of televisions.
(iv) Energy Saving Potential:
– It is roughly estimated that the potential energy saving is relatively high.
(v) Others:
– During the legislative process of the second phase of the MEELS in 2009,
enquiry was raised on inclusion of televisions into the MEELS. However,
televisions were not included into the second phase of the MEELS because
the new test standard (IEC 62087) was just released and the test standard
under Hong Kong voluntary energy efficiency labelling scheme (VEELS)
only applied to standby mode instead of on-mode. There was also no
accredited testing laboratory in Hong Kong to conduct on-mode test. Both
test standard and accredited testing laboratory are now available.
– The Government has proposed to include televisions into the proposed
mandatory producer responsibility schemes (PRS) on waste electrical and
electronic equipment (WEEE) with coverage of televisions with a diagonal
display screen size not exceeding 254 cm (100 inch).
– About 200 models have been registered under the VEELS.
3
Proposed Test Standards
10. Currently in Hong Kong, televisions are covered under the Voluntary Energy
Efficiency Labelling Scheme (VEELS). The energy efficiency performance of
television is measured and evaluated in accordance with IEC 62087:2008 (Edition 2.0)
“Methods of Measurement for the power consumption of audio, video and related
equipment” and the standby power of the television is measured in accordance with
IEC 62301:2005 (First Edition) “Household electrical appliances - Measurement of
standby power”.
Proposed Test Requirements
11. The following tests are required:
- On mode Power Consumption Test;
- Standby mode Power Consumption Test; and
- Visible Screen Dimensions Test.
Proposed Determination of Energy Efficiency Grading
12. With measured power consumption, an Energy Efficiency Index (EEI) is then
calculated for determination of its energy efficiency grade. The determination of EEI
of a television can be determined as below:
P
EEI =
where
Pref A
P
A
Pref A
= 20 Watts + ( A ÷ 100 ) × 4.3224 Watts/ cm2
= on-mode power consumption measured in Watts
= television visible screen area expressed in cm2
13. The proposed energy label is “Grading Type” and similar to the current MEELS. There
will be five energy efficiency grades, with Grade 1 being the most energy efficient and
Grade 5 being the least.

Section 3.2 - Washing Machines (7kg < Washing Capacity ≤ 10kg)
14. Considerations for Inclusion into the MEELS
The following information has been taken into account in considering inclusion of
washing machines (7kg < washing capacity ≤ 10kg) into the MEELS:
(i)
Overseas Practices:
(ii)
– Washing machines (7kg < washing capacity ≤ 10kg) are widely covered in
the mandatory labelling schemes of overseas economies (including Australia,
Canada, China, the European Union, South Korea and the United States).
Test Standards:
– International test standard is available for energy efficiency performance
measurement of washing machines.
(iii) Availability of Testing Laboratories:
– Accredited testing laboratories are available in Hong Kong for testing the
energy efficiency performance of washing machines.
(iv) Energy Saving Potential:
– It is roughly estimated that the potential energy saving is relatively medium.
(v) Others:
– About 100 models have been registered under the VEELS.
– It is estimated that the sales quantity of washing machines (7kg < washing
capacity ≤ 10kg) account for around 8% of total market sales.
Proposed test standards
15. Under the MEELS, washing machines (washing capacity ≤ 7kg) have been included. It
is proposed to include washing machines (7 kg < washing capacity ≤ 10kg) in the third
phase of the MEELS. The energy efficiency performance of a washing machine is
measured and evaluated in accordance with different standards based on the types of
washing machines:
―IEC 60456 for horizontal axis type washing machine, and
―JIS C 9606 for vertical axis type washing machine
Proposed Test Requirements
16. The following tests are required:
- Energy Consumption Test (kWh/kg/cycle);
5
-
Water Consumption Test (litres/cycle);
Washing Performance Test; and
Water Extraction Performance Test.
Proposed Determination of Energy Efficiency Grading
17. Energy efficiency grading of a washing machine is evaluated by the Specific Energy
Consumption (Esp), which can be calculated as below:
E
Wr
Esp =
where
Esp = Specific Energy Consumption (kWh/kg/cycle)
E = Measured Energy Consumption per cycle (kWh/cycle)
Wr = Rated Washing Capacity (kg)
18. The proposed energy label is “Grading Type” and similar to the current MEELS. There
will be five energy efficiency grades, with Grade 1 being the most energy efficient and
Grade 5 being the least.

Section 3.3 - Room Air Conditioners (Heat Pump)
19. Considerations for Inclusion into the MEELS
The following information has been taken into account in considering inclusion of
room air conditioners (heat pump) into the MEELS:
(i)
Overseas Practices:
With increasing application of reverse cycle technology in air conditioning in
recent years, it allows air conditioners to operate at reverse cycle, including
cooling mode and heating mode (i.e. heat pump). Room air conditioners (heat
pump) are covered in the mandatory labelling schemes of some overseas
economies (including Australia, China, the European Union, South Korea and
the United States).
(ii) Test Standards:
–
International test standard is available for energy efficiency performance
measurement of room air conditioners (heat pump).
(iii) Availability of Testing Laboratories:
–
Accredited testing laboratories are available in Hong Kong for testing the
energy efficiency performance of room air conditioners (heat pump).
(iv) Energy Saving Potential:
–
– It is roughly estimated that the potential energy saving is relatively medium.
(v) Others:
–
Some economies (for example, China and the European Union) adopt one
energy label to indicate both cooling and heating energy efficiency
performance while some (for example, Australia) adopt two energy labels to
separately indicate cooling and heating energy efficiency performance.
–
In determining the heating energy efficiency performance of room air
conditioners (heat pump), it is necessary to construct the bin temperature
distribution and corresponding operating hours in accordance with the data to
be obtained from the Hong Kong Observatory.
–
Under the existing MEELS, there are about 400 listed models of room air
conditioners which can operate at reverse cycle, including both cooling and
heating functions. Currently, only their cooling functions are evaluated for
energy efficiency grading under the MEELS.
7
Proposed Test Standards
20. Room air conditioner (heat pump) is not currently covered under VEELS. It is
proposed to use “Heating Seasonal Performance Factor” (HSPF) for evaluation of the
energy efficiency performance of room air conditioner (heat pump).
21. HSPF is briefly defined as “the ratio of total annual amount of heat that the equipment,
including make-up heat, can add to the indoor air when operated for heating in active
mode to the total annual amount of energy consumed by the equipment during the
same period.” Therefore, it is an evaluation of the energy efficiency performance of a
room air conditioner (heat pump) over a time period.
22. The energy efficiency test under the current MEELS for room air conditioners (cooling
only) is conducted according to ISO 5151 “Non-ducted air conditioners and heat
pumps – Testing and rating for performance” and ISO 16358-1 “Air-cooled air
conditioners and air-to-air heat pumps - Testing and calculating methods for seasonal
performance factors (Part 1): Cooling seasonal performance factor” for determination
of the cooling mode energy performance. It is proposed to adopt international standard
ISO 16358-2 “Air-cooled air conditioners and air-to-air heat pumps - Testing and
calculating methods for seasonal performance factors (Part 2): Heating seasonal
performance factor” to evaluate the heating performance of room air conditioners
(heat pump).
Proposed Test Requirements
23. For determination of heating mode energy performance, the following test
requirements for different types of room air conditioners are required in accordance
with ISO 5151 and ISO 16358-2:
Fixed capacity room air conditioners (one test point at full load);
Inverter room air conditioners (two test points, one at full load and one at 50%
full load); and
Maximum Heating Performance Test.
8
Determination of Energy Efficiency Grading
24. Based on the above proposal and the calculation method as specified in ISO 16358-2,
the HSPF of a room air conditioner can be determined as below:
HSPF
=
Heating Seasonal Total Load
Heating Seasonal Energy Consumption
25. The proposed energy label is “Grading Type” and similar to the current MEELS. There
will be five energy efficiency grades, with Grade 1 being the most energy efficient and
Grade 5 being the least.

In accordance with the international test standard, only standing loss is
measured to evaluate the energy efficiency performance of electric storage
water heaters.
Proposed Test Standard
27. Currently in Hong Kong, electric storage water heaters are covered under the VEELS.
The energy efficiency performance of electric storage water heaters is measured based
on IEC 60379 “Methods for measuring the performance of electric storage water
heaters for household purposes”. With measured power consumption, an Energy
Efficiency Index (EEI) is then calculated for determination of its energy efficiency
grade.
Proposed Test Requirements
28. The following tests are required:
- Energy Consumption due to Standing Loss (kWh/year);
- Rated Capacity Test;
10
-
Hot Water Output Test; and
Reheating Time Test.
Determination of Energy Efficiency Grading
29. The proposed energy efficiency grade for electric storage water heater is determined as
below:
Energy Efficiency Index ( I) = ( Est,var / Est,av,var ) x 100 %
where
Est,var
= the energy consumption of the tested heater due to standing loss (the
variable component) per 24 hours (kWh/24h) , as given by equation (1)
below
Est,av,var = the average appliance energy consumption due to the variable component
of the standing loss, per 24 hours (kWh/24h) , as given by equation (2)

as given in Table A below
The average appliance energy consumption, due to variable standing loss, is given by:
Est,av,var = Est,av – Est,fix
............................... (eq.2)
where
